METHOD oF AND APPARATUS FOR LINING CLOSURE ELEMENTS.

' Application filed November 28, 1924. Serial No. 752,728

The present invention relates to a method of and apparatus for liningclosure elements for containers.

One object of the invention is to provide an improved method, by whichthe production of large numbers of insulated closures for containers andthe like may be rapidly efiected in an economical and eflicientmanner.More particularly, the present method embodies the intermittent feedingof a series of closure elements to a predetermined point of operation,the feeding of suitable lining material in proximity to sa-idpoint, thesevering of blanks of the proper size from said material, and theapplication of the blanks to the. closure elements. 7

Another object of the invention is to provide an improved machine inwhich the coordination of the operations necessary to assemble theclosure elements and to form and apply the insulating blanks thereto iscarried out in an efiicient and economical manner. I

Still another object of the invention is to provide a simple, efiicientand dependable machine which will intermittently feed a series ofclosure elements toa predetermined point upon a support and which willautomatically and intermittently feed a strip of sheet material intoregistry with the closure elements at said point and sever blanks fromthe strip and apply the same to the closure elements the severaloperatingmechanisms being coordinated to perform the differentoperations in proper timed relation.

To these and other ends the invention resides in certain improvementsand combinations of parts, all as will be hereinafter nore fullydescribed, the novel features being pointed out in the claims at the endof the specification. v

Figure 3 is an enlarged sectional elevation taken on line 3 3- of Figure1, and illustrating the means for severing and applying the blanks ofinsulating material to the closures; I

Figure 4 1s an enlarged-fragmentary. sectional elevation through theclosure and the crimping die with the latter shown in its lowermostposition upon the former;

a Figure 5 is a top plan of a portion of the Figure 7 is a diagrammaticView in ele-- vation showing one of the closures upon the feed bar withthe blank in position to be applied to the closure by the crimping die.

Similar reference numerals throughout the several views indicate thesame parts.

i The present invention embodies an improved machine for effectingautomatic advancement of a series of closure elements preferably of theflanged or curled edge type to a predetermined blank applying positionand includes means for intermittently feeding lining material to a pointin proximity to the blank applying position, together with automaticmeans for successively severing blanks from said material and meansoperated in timed relation thereto for applying the severed blanks tothe closure elements, either by crimping the blank upon the 010- sureelement or by forcing its peripheral edge'portion behind or under aninwardly inclined or curled flange thereof, or' both as may be desired.

The closures or covers thus produced are adapted preferably toconstitute the end walls of a well known type of paper container now inuse, but may be employed in connection with any type of containerrequiring a lined or insulated cover or wall, said closures beingsuitably applied to the body of the container, as by crimping, or in anymanner desired. The containers are preferably both air and liquid tightand are sanitary and extremely light in construction and of a durablenature.

In the drawings I have shown a frame 1 having a table 2 thereon andupright extensions3 at one side thereof. An anvil or bed plate issuperimposed upon the table and preferably comprises the spaced platemembers 4 and 5, shownin Figures 2 and 3, and are adapted to support theclosures 6 while the blanks of insulating material 7 are being appliedthereto by the inserting and crimpcomprises a reciprocably mounted head11 I manner shown in Figure l,

blanks are cut from a sheet or stripof paper 9, or any otherlmaterialsuitable for insulat ing the contents of the containers from the metalend closures thereof. The paper strip, which is of a width slighlygreater than the diameter of the blank ,7, is intermittentlyj i fedfrom a roll 10 into registry with the inserting or crimpingdie a nd theclosure thereunder by a suitable feed mechanism Which Will behereinafter ClGSGllbQd.

The blank severing means preferably having a ri ng shaped cutter 12adapted to cooperate with the annular cutting edge 13 of a die 14 havingan opening 15 in registry .with the anvil, the latter being adapted tosupport the closure centrally beneath the plunger 8 during the crimpingor blank applying operation. The. paper is fed across the upper face ofthe cutting die 1% beneath a cover 16] supported by strips 1'? whichform guides for the paper and which are suitably connected with the die14%, the cover l6'hav1ng an opening 18 large enough to accommodate thecutting ring '12 or'mov-v able partiof the severing die. The cuttingring 12 is shown in its lowermost position in Figure 3, with the severedblanks if in position to be moved down and applied to the closures bythe blank applying die 8, in the The head 11 whichcarries the cuttingring 12is suitably ings carried by 'the forwarr connected with thedepending portions 19 of across head 20 by means of the upper and lowerrings 21 and 22 and the screws 23 and 24 as shown in Figure 3. The crosshead 20 is guided in ways 25 on the arms 26 pro jecting fronithe uprightframe members 3, and 1s provided with extenslons 27 carrying rollers28which engage cams 29 'upon a crank shaft 30, Journaled in suitable'b a wr arms 31 at the top ofthe frame nie nbers The crank shaft is providedwith a flywheel 32 which may be driven by'a belt not shown, or by anymeanssuitable for operating the Shaftl 'Thecr ank shaft is provided witha 39 which is centrally" disposer upon the crimping die 8 asshownflinFigure 3. A springi-ZS, is interposed between the connec tion 37 and thebottom wall- 39 of the die, whereby to form a yieldable connectionbetween the crank shaft and the die, to avoid rupturing of any part ofthe mechanism.

The crimping or blank applying die is mounted to slide within the head11 carrying the cutting ring 12 and is reciprocated thei eby the crankshaft, while the cu'ttingring is reciprocated by the action of the cams29 and the springs 40 which constantly exert an upward pull onthe rods4-1, the'latter being connected with the rearwardly' projecting arms 42of the crosshead. The springs therefore serve to lift the cross head andthe cutter ring to theiri-highest position when the cams are in theposition shown in Figure 1'. 111 this position of thecams the offsetportion of the crank shaft is at itshighest point "and consequently thecrimping or blank inserting die is elevated the maximum amount," to theposition'indicated by the dotted lines in Figure 2', Rotationof thecrankshaft from the position indicated in Figure 2 in the directionindicated by the arrow will result in a downward movement of the crosshead which will carry the cutting ring through the paper to sever'theblanks as shown in igure 3. Following closely after the blankseveringoperationthe 'crank' shaft will "move the die 8 downw'ardly to carry theblank into engagement" with the closure and will both crimp it thereonand force its peripheral edge portion behind the inclined flange 43 ofthe closure, it being understood that the blank is out large enough toallow for the amount of material required to cover the beveled portionsti and 45 of the closure, as indicated in Figure 6.. The blank applyingportion 'of' the die is so shaped as to'e'ffectively draw the paperdownwardly upon the inclined portions 44 and l5 to crimp it thereon andat the same time is adapted to force the peripheral edge portionf lfi ofthe blank "be-- hind the inturned flange '43 and-into engagement withan'a-nnu'lar portion 47 of the closure, .as shownon an enlarged'scale inFigure 6. The crimping action gives a permanent set to the blank,corresponding to the shape of the closure so that the blank will remainin proper position upon the latter after it has been secured tothe'botton'r of thecontaineror to the "movable end cap therefor, astheca'se. may her The exter nal appearance ofth'eblank when-crimpedupon'the closure is substantially as indicated by the finished closureshown at the right of Figure 5,'which is at a point upon the anvilcorresponding to'th'at shown in Figure 3, or in other words, in positionto register. with the crimping die. V I

Although I have shown a dished form of closurc,it will be understoodthat my improved methodcontemplates the application of the lining blanksto closures, either of the dished or substantially flat type or of theflanged or nonflanged type, and. embodies the forcing'of the peripheraledges of theblanks behind the flanges of the closures, re

gardless of whether or not the shape of the.

closure is such I as to require a crimping action of the blank inapplying it' to the closure. The J closure when completed, shown inFigure 6,are applied to the con thereon by a crnnping or seamingoperation or in any well known manner.

The closures are advanced upon the bed plates or anvil bars 4 and 5between suitable guide bars 48 and 49, the former being fixed upon thebed plate 4 and the latter yieldably mounted upon the bed plate 5, bymeans of springs 50, havingtheir inner ends seated upon the guide bars49 and their outer ends upon a plate 51, the springs being carried bythe stems 52 guided by the plate 51. Studs 53 project into slots 54 ofthe bars 49 and limit the movement of the." latter with respect to theclosures. Both guide bars 48 and 49 are beveled as indicated at 55 toreceive the inturned flanges 43 of the closures, whereby to hold theclosures properly seated upon theanvil bars during their advancement toblank applying position. i v

The feeding mechanismfor the covers or closure elements 6 preferablycomprises a 'reciprocably mounted bar 56 movable between the bed platesoranvil bars 4 and 5. The feed bar is provided with a series o-f fingersor projections 57 adapted to engage the closures as shown in Figure 5 toadvance them step by step int-o registry with the crimping die wherethey remain long enough to have the lining applied thereto, the fingersbeing disposed in recesses formed in the bar and yieldably pressedupwardly by springs, not shown.

-An extension frame 58 is carried by the main frame 1 to support aholder for a series of flanged or curled closure elements as shown inFigure 1. The holder may be constructed in any desired manner, butpreferably comprises a plate 59 having upstanding guides 60 for theclosures and is provided'with an opening 61 slida-bly larger than thediameter of the closure elements to permit them to descend by gravityupon a pair of spaced plates 62, only one of which is shown, and betweenwhich the feed bar operates to successively engage and advance thelowermost closure of the stack through engagement of the outermostfinger 57 of the bar with said closure when the bar begins to advancetoward the crimping die from its extreme outer position, as shown inFigure 1. The feed bar may be provided with any desired number of thefingers 57 preferably 5, each of which advances a closure one step forevery forward stroke of the bar. On the return stroke of the barthe'yieldably mounted fingers ride under the closures and thenmove backto normal position ready to advance the closure elements when the bar isagain moved forwardlv. Upon advancement of the bar from the positionshown in Figure 1, the front closure, upon which a blank has beenapplied, will be pushed forward and the second closure brought into tingrin and the die for applying the bla registry with the crimping die,while at'the same time each succeeding closure overlying the bar will beadvanced one step. The

closures to which the blanks have been applied will be pushed forward bythe advancement of the succeeding closures and carried to the desiredpoint of discharge, preferably to a chute, not shown. However, ifdesired, additional fingers may be disposed upon the front end of thefeed bar to successively engage and advance the completed closures tothe desired point of discharge from the machine. I

In order to insure the proper feeding of the closures between the'rearends of the guides 48 and 49 when the closures are passing thereto fromthe guide plates 62, I have pro vided between the guide bars a pair ofshoes 63 connected with upwardly extending rods (54 and 65 which projectthrough and are guided by a plate 66 supported by posts 67 on the frame58, the receiving ends of the shoes being inclined upwardly so that theclosures will more readily pass beneath the shoes, which are yieldablyheld in engagement with the closures by suitable springs 68 as shown inFigure 1.

Reciprocation of the feed bar in proper timed relation to the movementsof the out to the closures may be effected by any suitable means, butpreferably by means actuated by the crank shaft. This is done in thepresent instance by a pitman 69 having its upper end connected with acrank disk 70 on the fly wheel end of the crank shaft and its lower endconnected with an arm 71 on a rock shaft 72 journaled in the sidemembers 73 of the frame 1. The rock shaft carries an upstanding arm orlever 74 which is pivotally connected with the front end of a link 75,therear end of which is connected with an arm 76 depending from the feedbar as indicated in Figure 1. It will be readily seen that'upon eachrevolution of the crank shaft the feed bar will be advanced from andreturned to the position shown in Figure 1, or in other words, acomplete operation of the same will be effected,

The paper feed mechanism, as before stated, may be of any well knowntype, but preferably comprises a pair of feed rolls 77 and 78 mountedone above the other upon suitable brackets 79 as shown in Figure 2.

The upper roll is yieldably held in engage-.

ment with the paper by springsSO and is provided at one end with adriving gear 81 having an overrunning clutch, not shown, the gear beingpreferably operated by a rack 82 actuated by a pitman 83 driven by acrank disc 84 on the crank shaft 30 as shown in Figure 2. By thismechanism the paper riod of Withdrawal of the crimping die from blankapplying position. 7
